Sewer network stability and reliability factor
Outcome; We take care of your wastewater and protect you and the environment from sewer flooding Description; An overall assessment of the long-term stability and reliability for the waste water networks. It’s based on a series of measures which include sewer collapses, sewer blockages, properties flooded due to overloaded sewers and other causes, certain types of pollution incidents and reactive equipment failures.

Technical details specific to reference bandings Reference and Upper Reference refer to the bandings that determine whether a performance commitment is improving, stable or deteriorating, with an overall assessment taken by way of a calculation of the sub-measures (rows 14-20 page 214 as detailed above). The first assessment is the overall status of the main S&R measure as either; Improving, Stable or Deteriorating. This assessment is reported annually with confirmation of the end of AMP position made in year four based on the year five forecast outturn position. Sub-measures will be judged as either Stable, Improving or Deteriorating depending on their position in relation to the reference levels set at PR14 and confirmed in Ofwats ‘FD[final determination] Outcome and ODI[outcome delivery incentives] base dataset’. The number of sub-measures’ categorisation will then be aggregated to confirm the overall assessment for the overall S&R measure. To make sure that our assurance methods are robust, independent technical assurance is provided by Halcrow.
